Phase II OPALESCENCE Study of TLX250-CDx in Triple Negative Breast Cancer to be Presented at SABCS

Melbourne (Australia) | 30 November 2023

Telix today advises that the completed Phase II OPALESCENCE investigator-initiated trial (IIT) of its carbonic anhydrase IX (CAIX)-targeting positron emission tomography (PET) imaging candidate, TLX250-CDx (89Zr-DFO-girentuximab), in patients with triple-negative breast cancer (TNBC), will be presented at the 2023 San Antonio Breast Cancer Symposium® (SABCS) taking place from December 5-9, 2023.

Dr. Caroline Rousseau, Principal Investigator for the OPALESCENCE study ( ID NCT04758780) at the Institut de Cancérologie de l’Ouest (ICO) in St Herblain (France), will deliver top-line results as a poster presentation at 5pm CT on Wednesday December 6.

The primary objective of the OPALESCENCE study was to evaluate how CAIX-targeted imaging with PET can be utilised for the diagnosis and staging of TNBC and to develop a deeper understanding of CAIX as a potential therapeutic target in this patient population with a significant unmet medical need. 

SABCS is the largest and most prestigious scientific gathering on breast cancer research worldwide. Visit for more information on the congress.
